The nerve! Electricity in our bodies

Neuron cell body with dendrites and synapses

Your body is making and using electricity all the time — but how do we do it? We’ll take a look at how bioelectricity helps our brain sends signals and our hearts pump blood. And we’ll learn about some amazing animals that use electricity in weird and wild ways. (This is the fourth of a four-part series)

This is the fourth in a four-part series:

• Part One: Shocking! The science of static

• Part Two: High voltage! How electric power reaches your outlet

• Part Three: Charged up! The science of batteries

Special thanks to the Bakken Museum in Minneapolis for their help with this series!
